2 Claims.

The present invention refers to new and useful improvements in thesteering of motor vehicles or any other kind of vehicles.

The steering of vehicles based on the principle of simultaneous andparallel deviation of the front wheels has been known heretofore.

My invention is based on an entirely new principle, the principle of thesimultaneous and parallel deviation of the four wheels and thesimultaneous but contrary deviation of the front and rear wheels.

My invention also provides the means or device for carrying int practicethis new principle, which improves and facilitates the steering ofvehicles.

The means I have devised for this purpose comprises a steering gear caseprovided with two steering arms and other parts which, while a1 lowingthe steering of vehicles in the usual and known manner, i. e., thesimultaneous and parallel deviation of the two front wheels, it permits:

First, the simultaneous or parallel deviation of the front and rearwheels, and

Second, the simultaneous but inverse deviation of the front and rearwheels, which makes the taking of curves by and the parking of vehicleseasier and safer.

The simple enunciation of my principle for the steering of vehicles andthe description of my device for carrying my principle into practice.all of which permits the movements not known heretofore in vehicles, issuflicient, for those versed in the art, to exactly appreciate theimportance of my invention.

In order that my invention may be easily understood and carried intopractice, I have illustrated it in the accompanying drawings, in whichFig. 1 is a front view in elevation of my steering gear case showing thetwo steering arms and the direction rod adjacent to the steering post.

Fig. 2 is a view in elevation of the left end of the steering gear caseshowing the rear wheel steering arm with its coupling teeth.

Fig. 3 is a view in elevation of the right end of the steering gear caseshowing the front wheel steering arm.

Fig. 4 is a longitudinal section in elevation on the line P--L of Fig.2.

Fig. 5 is a cross section in elevation on the line A--B of Fig. 4.

Fig. 6 is a cross section in elevation on the line C--D of Fig. 4.

Fig. '7 is a cross section in elevation on'the line E--F of Fig. 4.

Fig. 8 is a cross section in elevation on the line G-H of Fig. 4.

Fig. 9 is a plan view of the vehicle frame showing' the steering gearcase and its connecting parts to the front and rear wheels.

Fig. 10 is a side View in elevation of Fig. 9.

Fig. 11 is a front view in elevation of Fig. 9.

Fig. 12 is a rear view in elevation of Fig. 9.

Fig. 13 is a plan view of the frame showing the direction rod fordeviating the front wheels while the rear wheels are in normal position.

Fig. 14 is a plan view of the frame showing the direction rod forsimultaneously deviating both the front and rear wheels in inversedirection.

Fig. 15 is a plan view of the frame showing the direction rod forsimultaneously deviating both the front and rear wheels in the samedirection, or parallel.

In all these figures the same number of reference indicates the samepart.

My device for carrying into practice my new principle in the steering ofvehicles comprises a steering gear case I which has a steering arm 2 forthe front wheels, a, steering arm 3 for the rear wheels, and a directionrod 4 adjacent to steering post 5.

Steering post 5 is provided with a worm 6 which engages gears l and 8.

Gear 1 is securely mounted on countershaft 9 which carries gear l0 andsteering arm 2 so that when it is made to revolve by means of steeringwheel ll of steering post 5 to the right or to the left the steering arm2 moves correspondingly backwards or forward.

Gear 8 is provided with lateral coupling teeth l2 and is freely mountedon countershaft I 3 on which is also mounted gear M with lateralcoupling teeth I2, and a coupling bushing IS with corresponding couplingteeth I2" at both ends.

Bushing I5 is securely mounted on countershaft l3 and has a groove l6which engages a collar I1 which is operated by a fork l8 at the end ofdirection rod 4.

Direction rod 4 is provided at its upper end with a lever l9 and at itslower end, inside steering gear case I, with the aforementioned fork ISwith the collar I! which engages groove [6 of bushing l5. By means oflever l9 which operates direction rod 4 it is possible to longitudinallychange the position of bushing l5 and countershaft l3 so that whenbushing l5 engages gear 8 by means of teeth I2 and I2" steering arms 2and3 move in opposite directions and when bushing [5 engages gear M bymeans of teeth l2 and l2" steering arms'2 and 3 move in the same direction.

Gear I4 is freely mounted on countershaft l3 and engages transmissiongear 20, freely-mounted on axle 2| securely fixed on case I, which inturn engages gear l securely mounted on countershaft 9.

Rear wheel steering arm 3 is provided with teeth 22 which engagecorresponding grooves 24 in piece 23 fixed to steering gear case I, sothat when that part of the device formed by bushing l5, countershaft l3and steering arm 3 is in a neutral position or disengaged, steering arm3 is securely held by teeth 22 and corresponding grooves 24, so thatwhen steering post is operated it will only operate steering arm 2, andconsequently only the front wheels will have a directional movement.

From the foregoing it will be gathered that the means I have devised andmad known in the foregoing specification permits carrying my newprinciple into practice, 1. e., the principle of the simultaneous orparallel deviation or movement of the front and rear wheels of avehicle, or the simultaneous but contrary or inverse deviation of thefront and rear wheels of the vehicle.

It is understood that the means ordevice above referred to may besubject to constructional changes'without departing from the scope ofthe invention as made known in the followin claims. I I claim:

1. In a device of the character described, a casing, a countershaftextending thereacross and joumaled in the walls thereof, amotion-transmitting arm secured to said countershaft, a slid- .ablecountershaft extending across said casing in spaced parallel relation tosaid first countershaft, said slidable countershaft also being journaledin said casing walls, a motion-transmitting arm secured to said slidablecountershaft, and means for selectively actuating said countershafts andtheir respective motion-transmitting arms to simultaneously rotate bothshafts in the same direction, to simultaneously rotate both shafts inopposite directions and to rotate said first countershaft alone ineither direction; said means comprising a gear fixed to said firstcountershaft adjacent one end thereof, asear loosely mounted on thecorresponding end of said slidable countershaft, a manually operableactuating member in engagement with said gears, a gear fixed to saidfirst countershaft adjacent the other end thereof, a corresponding gearloosely mounted on the other end of said slidable shaft, an intermediatefreelyrotatable gear intermediate said last two gears and insimultaneous engagement therewith, and
